X2Chat

X2Chat - Secure Messenger Built for Privacy

X2Chat is a modern, privacy-first messenger that puts you in control of your data. Every message, file, and call is protected with end-to-end encryption. No one in the middle - not us, not your provider - can read your conversations.

END-TO-END ENCRYPTION

• RSA-2048 for session key exchange
• AES-256-GCM for content (text, files, media)
• WebRTC Insertable Streams for calls - true E2E at the RTP-frame level
• Trusted-key QR codes - MITM protection from the server itself

CALLS FAST AND CLEAR

• High-quality 1-on-1 and group audio/video calls
• Ultra-low latency through an optimized audio pipeline
• Native CallKit integration - lock-screen calls feel like system calls
• Adaptive bitrate and resilience on weak networks

CLOUD BACKUP WITHOUT COMPROMISE

• Encrypted backup secured with your own password
• Account restore on a new device via slot_id and password
• iCloud Keychain sync for seamless device migration

PRIVACY BY DEFAULT

• Zero ads, zero tracking
• Minimal metadata stored server-side
• Open encryption architecture

X2Chat fits private conversations, work communications, and everything that should stay strictly between you and your contact.
